ab: Summary: In teaching mathematics, we encounter visual models in taking new
curriculum frequently. In our paper, we focus on the multiplication
rule in probability using two visual models: tree diagram and tangram.
First, we introduce the topic and analyse the occurrence of visual
models in selected textbooks of mathematics for high schools. The main
part of the paper is devoted to the analysis of the percentage of
correct solutions of probability problems using visual models.
According to the visual model, we analyse two worksheet tasks.
Regarding to the multiplication rule in probability, we discuss
pupil’s solutions of the “tree diagram” worksheet firstly and of
the “tangram” worksheet secondly. Our analysis shows that pupils
achieve better learning outcomes when they worked with the visual model
“tree diagram”.
